Solve the problem.Sandy manages a ceramics shop and uses a 
kiln to fire ceramic greenware. After turning off her kiln, she must wait until its temperature gauge reaches 
before opening it and removing the ceramic pieces. If room temperature is 
and the gauge reads 
in 13 minutes, how long must she wait before opening the kiln? Assume
